International audience A new approach is proposed for determining earthquake hypocenters aimed at a more comprehensive characterization of its uncertainty and ambiguity. Application of the new approach to study the seismic focal subduction zones and volcanic seismicity is discussed by the example of the data of the Kamchatka Branch of the Geophysical Survey of the Russian Academy of Sciences. В работе предложен новый подход к определению гипоцентров землетрясений, направленный на более полную характеризацию его неопределённости и неоднозначности.
